Abstract
An ultrasonic-motor-driving device is provided which allows fine adjustment of the periods of driving waves that are generated by a driving-wave-generating portion. A driving device for an ultrasonic motor includes a driving-wave-generating portion. The driving-wave-generating portion generates signals for driving piezoelectric elements included in the ultrasonic motor. The driving-wave-generating portion is constructed capable of generating rectangular waves including a plurality of rectangular waves with different periods.
